METALLIC MAT.

Patented Dec. 5, 1905.

Application filed November 18, 1903 Serial No. 181,643.

To all whom it may concern.- I

Be it known that I, PETER J. SHRUM, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Metallic Mat, of which the following is a full, clear, and exact description, reference being had to the acpanying drawings, forming part of this specification, in which Figure 1 is a plan View showing a mat provided with my improved finish. Fig. 2 is a side elevation of the same; and Fig. 3 is an end view, partly broken away.

My invention relates to that class of metallic mats wherein sections having open meshes are hinged to each other upon rivets or hingerods to give a flexible mat; and the object of the invention is to strengthen and improve the side finish on the side edges of mats.

In the drawings I show a mat in which each section is composed of short bent strips 2 with end legs 3. The legs of the adjacent sections are strung upon the hinge-rod 4, which extends transversely of the same. The end portions of each hinge-rod are extended to form the portions 3, which extend longitudinally of the mat and are provided with end hooks 5, engaging the bends of the next hinge-rod. I preferably provide within the portions 3 of the hinge-rods the flat strips 6, which close the half-mesh portions at the side. At the end of the mat the hooks 5 of the hinge-rods engage a transverse finish-rod, which may be either single, as shown at 7 at the left-hand end, or double, as shown at 8 at the right-hand end. At the left-hand end the hinge-rod 4 extends through the legs of the last section and the wire or rod 7 extends outside the ends of the legs and is looped at its ends 9 around the hinge -rod. At the right-hand end the hooks 5 engage the ends of the double wire 8. One leg of this wire extends through the holes in the legs 3, while the other leg extends parallel therewith be yond the legs. The ends of this double wire may be bent around, as shown at 10. To complete the end finish, I preferably employ spacers upon the double end rods, which spacers may be of spirally-twisted form, as shown at 11. I preferably make these spacers of one length of wire twisted into closed spirals between the legs with an opened spiral to pass the legs.

The advantages of my invention result from the edge-finish form by the interengagement of the end portions of the hinge-rods. This gives a strong finish and also presents a neat appearance.

The meshes may be formed by longer strips and in different ways, the hinge-rod may be in the form of rivets, and many other changes may be made in the form and arrangement of the parts without departing from my invention.

I claim 1. A flexible metallic mat having meshes formed of bent metal strips and provided with hinge-rods having bent end portions located below the wearing-surface, said end portions of adjacent rods engaging each other;

substantially as described.

2. A flexible metallic mat having meshes formed of bent metal strips and provided with hinged rods having bent extensions located below the wearing-surface, the extensions of'one rod embracing the next rod; substantially as described.

3. A flexible metallic mat having an end rod or finish-bar and a hinge-rod with hooked ends located below the wearing-surface embracing the end bar; substantially as described.

4. A flexible metallic mat having a transverse rod and spiral spacers thereon formed of a continuous length of wire with some of the spirals spread apart to receive the meshlegs; substantially as described.

In testimony whereof I have hereunto set my hand. 7
